Hi Igor,
In i.MX8QM "register_programming_aid" excel file, 'DDR CFG file' sheet was there, which is missing in i.MX8MQ "register programming aid" excel sheet. Is that not needed in case of i.MX8MQ?
Kindly let me know.
Thanks and Regards,

Dear Igor,
Kindly let me know what bl31.bin (ATF binary) does?
In what case we need to do changes in 'lpddr4_ddrc_cfg.c' file?
Thanks in advance.
